Abstract

An emulsion aggregation (EA) toner includes an amorphous polymeric resin, optionally a colorant, and a small molecule crystalline organic compound having molecular weight less than 1,000 g/mol and melting point less than the fusing temperature of the EA toner, wherein a mixture of the resin and the small molecule compound is characterized by a reduction in glass transition temperature from that of the resin and by the lack of a significant solid to liquid phase transition peak for the small molecule compound as determined by differential scanning calorimetry, the enthalpy of fusion for the small molecule compound in the mixture being measured to be less than 10% of the enthalpy of fusion of the compound in pure form. Furthermore, the EA toner may be configured to have a crease fix minimum fusing temperature (MFT) less than or equal to the crease fix MFT of a benchmark ultra-low-melt emulsion aggregation toner.
